Do you have a requirement for specialised functionality built on Concrete CMS?

Compare your site environment with another site environment.

Have you ever been trying to track down a Concrete CMS site problem and wondering if it is environment related?

Have you sat with two environment pages side by side and gone cross-eyed working out what the differences are?

Are you frustrated by the tedious process of saving site environments into text files and running a diff application, only to get a diff that doesn't  understand the nuances of the Concrete CMS environment?

Install Environment Diff, paste in the environment from another site, and see the two environments side-by-side with differences highlighted. Dashboard page at Dashboard > System & Settings > EnvironmentEnvironment Diff.

Installs to Concrete v8.5.12 and version 9.any. Compares site environments from way back.
